Release notes on main website is not complete

Description

The Release Notes on the Documentation section (​http://www.pcbsd.org/en/release-notes.html) of the main website is not complete. It just contains Hardware Requirements, Software Specs and Available Packages. It should contain the complete Release Notes from the one announced on the mailing lists or the one from the PC-BSD blog. There should also be a link to the FreeBSD Release Notes to give access to users when users want to read also the FreeBSD Release Notes.
